Hi!

Thanks for your feedback
In scripts, can use the « setMessage » function. For your example, just add this line in your cursor creation :

run("setMessage current 20, osc://127.0.0.1:57120/track/1/fx/1/fxparam/" + circleIndex + " ");

To switch on or off an object, you can use the setActive function :

run("setMessage current 20, direct:// setActive  <0|1>");

Of course, you can mix messages like that (example) :

run("setMessage current 20, osc://127.0.0.1:57120/track/1/fx/1/fxparam/" + circleIndex + " 1, direct:// setActive " + (circleIndex-1) + " 0");

Good luck in your sequencer project !
